ATLANTA -- Corey Maggette and Milwaukee's reserves led the Bucks to their first winning streak of the season and left the stunned Atlanta Hawks with a three-game losing streak.
The Hawks began the season 6-0 before the three consecutive losses, including two at home. The lopsided loss to the Bucks stunned the Hawks.
"It's hard to explain," Hawks center Al Horford said. "I don't understand what happened."
The Bucks struggled with their offense early in the season and were last in the league in scoring with only 89.6 points per game before taking a 107-80 victory against the New York Knicks on Tuesday night.
Maggette had 20 points and Brandon Jennings added 19 as the Bucks took back-to-back victories for the first time this season.
The Bucks trailed by 13 points in the opening period before taking a lopsided 33-14 advantage in the second period for a 54-40 lead at the break. The bench led the second-quarter surge.

"We've got to give our bench a lot of credit tonight," Bucks coach Scott Skiles said. "They came out and not only got us back in the game but, I believe, we had a 27-point turnaround in the first half."
The Bucks continued to stretch the lead after halftime. Jennings had back-to-back 3-pointers late in the third period to stretch the advantage to 30 points at 88-58.
"When adversity hit us in the face, we went our separate ways," said Atlanta's Josh Smith, who had eight points and eight rebounds. "We'll figure out what's going wrong, and we'll fix it really quick."
Skiles said the Bucks should receive a confidence boost from the victory.
"Hey, look, if you come in here and are up  points over the Hawks, you're obviously doing something right out there," Skiles said.
Ersan Ilyasova had 17 points and John Salmons had 16 for Milwaukee.
Backup center Zaza Pachulia led the Hawks with 16. Horford had 14 points but only six rebounds as the Bucks took a 44-32 advantage on the boards.
Horford had 10 points in the first period as Atlanta's starters claimed a 20-7 lead. The advantage began to disappear when Hawks coach Larry Drew began substituting.
"Our starters have gotten us off to fast starts," Drew said. "I'm not getting the energy from the bench. ... That's the third game that's happened to us. I have to find better combinations to use that can sustain the energy."
The Hawks were stretched to seven games before beating the Bucks in the first round of the playoffs last season.
"This is a whole new season," said Milwaukee's Andrew Bogut, who had eight points. "People are going to build this rivalry up because they beat us in the playoffs, but it's pretty much a whole new team."
The Hawks couldn't match the Bucks' intensity, especially in the second and third periods, when Milwaukee outscored Atlanta 67-33.
Drew said his players were too easily frustrated.
"When it gets a little tough, we have a tendency to hold our heads down," Drew said. "I don't want to see our guys hang their heads."
Joe Johnson made only 5 of 13 shots for 13 points. A highlight for the Hawks was rookie Jordan Crawford, who set a personal high with 11.
